  1. Identification of the A293 (AVE1231) Binding Site in the Cardiac Two-Pore-Domain Potassium Channel TASK-1: a Common Low Affinity Antiarrhythmic Drug Binding Site.

  2. The results of the present study suggested that miR138 promoted proliferation and suppressed mitochondrial depolarization of human pulmonary artery smooth muscle cells by targeting TASK1.

  3. Screening for mutations in the human TASK-1 gene in 155 cases of sudden infant death syndrome (SIDS) was inconclusive. Results are suggestive for an increased hypoxia-sensitivity of neonatal TASK-1(-/-) mice, however, without causing an increase in neonatal lethality. In adult female TASK-1(-/-) mice respiration was unaffected, whereas adult male TASK-1(-/-) mice showed a modified breathing pattern.

  4. Recent studies show that modulation of TASK-1 channels, either directly or indirectly by targeting their regulatory mechanisms, has the potential to control pulmonary arterial tone in humans. Furthermore, mutations in KCNK3 have been identified as a rare cause of both familial and idiopathic pulmonary arterial hypertension. [review]

  5. Sequencing of BMPR2, CAV1, and KCNK3 coding regions did not identify any pathogenic variants in these genes in infants with pulmonary hypoplasia and pulmonary hypertension.

  6. Heterozygous KCNK3 mutations in pulmonary arterial hypertension lead to variable loss of channel function via distinct mechanisms.

  7. Familial cases of Pulmonary Arterial Hypertension related to heterozygous missense variants in the KCNK3 gene (encoding the two-pore-domain potassium channel TASK-1) has been described with a prevalence of 1.3 and 3.2% in idiopathic Pulmonary Arterial Hypertension and heritable Pulmonary Arterial Hypertension, respectively.

  8. our study indicates that TASK-1 is functionally regulated by caveolin-3, possibly via association with each other on the cell surface. These results point out a novel mechanism in the regulation of TASK-1.

  9. A burden of rare variants in BMPR2 significantly contributed to the risk of pulmonary arterial hypertension. In the remaining one family, the patient carried a pathogenic variant in a member of potassium channels, KCNK3, which was the first replicative finding of channelopathy in an Asian population.

  10. The results suggested that heterodimerization of TASK1 and TALK2 provides cells with the ability to make multiple responses to a variety of physiological and pharmacological stimuli.

  11. Genetic variation in the KCNK3 gene may contribute to Blood pressure variation and less severe Hypertensive disorders in which aldosterone may be one of several causative factors

  12. Knockdown of TASK-1 by siRNA significantly enhanced apoptosis and reduced proliferation in Non-Small Cell Lung Cancer A549 cells, but not in weakly TASK-1 expressing NCI-H358 cells.

  13. The present report supports the contribution of KCNK3 mutations to the genetic etiology of Pulmonary arterial hypertension and strongly suggests that mutations in KCNK3 follow incomplete dominance with worsening of the clinical features in homozygous patients.

  14. In a cohort with idiopathic or hereditary pulmonary arterial hypertension, a possibly associated mutation was found in 11.10% of the idiopathic cases (n = 16) and in 68.18% of the hereditary cases. There were 3 mutations found in KCNK3.

  15. Functional alanine-mutagenesis screens of TASK-1 and TRAAK were used to build an in silico model of the TASK-1 cap.

  16. control of TASK-1 trafficking by COPI, kinases, phosphatases and 14-3-3 proteins is highly dynamic.

  17. KCNK3 expression and function were reduced in pulmonary artery smooth muscle cells and endothelial cells in human pulmonary arterial hypertension.

  18. TASK-1 and TASK-3 may form heterodimers in human atrial cardiomyocytes.

  19. Diacylglycerol mediates regulation of TASK1 and TASK3 potassium channels by GNAQ.

  20. Enhancement of atrium-selective K(2P)3.1 currents contributes to action potential shortening in atrial fibrillation patients.

  1. TASK-1 channels displayed strong cardiac expression in mice. Dysregulation of atrial TASK-1 expression in murine atrial fibrillation and heart failure models suggests potential relevance of TASK-1 currents in arrhythmogenesis.

  2. studies demonstrate that TASK channels can limit ischemia-reperfusion damage in the cortex, and postconditioning with volatile anesthetics provides neuroprotective actions that depend, in part, on activation of TASK currents in cortical neurons.

  3. Whereas adult female TASK-1-/- mice had a virtually normal respiratory phenotype, except for an increased relaxation time, adult male TASK-1-/- mice exhibited enhanced ventilation that was mainly due to an increased tidal volume. Respiratory responses to hypercapnia and hypoxia were largely preserved. In neonatal TASK-1-/- mice, respiratory drive appeared reduced and knockout animals were more prone to experience apnea.

  4. Acute hypercapnia (5% CO2) stimulated ventilation in TASK-1/3(-/-) and wild-type mice to a similar extent; however, at higher CO2 concentrations the stimulation of ventilation was more pronounced in TASK-1/3(-/-) mice. At hyperoxia (100% O2), TASK-1(-/-), TASK-3(-/-) and wild-type mice showed the physiological small decrease of ventilation. TASK-1/3(-/-) mice exhibited an abnormal increase of ventilation under hyperoxia.

  5. Our results have uncovered a previously unknown role of c-Src tyrosine kinase in regulating interneuron function in the brain and identified a novel mechanism by which TASK-1 channels are activated in neurons.

  6. Adipose-specific Kcnk3 knockout mice display increased energy expenditure and are resistant to hypothermia and obesity.

  7. While there is compelling evidence that TASK-1 is involved in the pathogenesis of pulmonary arterial hypertension in humans, the mouse does not appear to serve as a suitable model to study the underlying molecular mechanisms

  8. the K(+) channel TASK1 controls the thermogenic activity in brown adipocytes through modulation of beta-adrenergic receptor signaling.

  9. KCNK3 channels are not involved in hearing.

  10. An important role for TASK-1 channels in limiting pancreatic alpha-cell excitability and glucagon secretion during glucose stimulation.

  11. This study showed TASK channels on cholinergic neurons contribute to endogenous EEG oscillations (including gamma activity) and the electrocortical response to histamine at the basal forebrain in vivo.

  12. Downregulation of TASK_1 increased proliferation rates of N2A cells.

  13. A glucose-dependent role for beta-cell TASK-1 channels of limiting glucose-stimulated Deltapsip depolarization and insulin secretion, which modulates glucose homeostasis.

  14. Oxygen and mitochondrial inhibitors modulate both monomeric and heteromeric TASK-1 and TASK-3 channels in mouse carotid body type-1 cells.

  15. This study demonstrated for the first time that oligodendrocytes express functional TASK-1 channels and provide compelling evidence they contribute to oligodendrocyte damage in hypoxia.

  16. TASK-1 deficiency does neither alter key electrophysiological parameters nor increases atrial/ventricular vulnerability after electrical stimulation.

  17. The PCR data revealed the existence of two astrocytic subpopulations markedly differing in their gene expression levels for inwardly rectifying K+ channels (Kir4.1), K(2P) channels (TREK-1 and TWIK-1) and Cl- channels (ClC2).

  18. No difference is found between the pulmonary artery (PA) of wild-type and TASK-1/3-deficient mice; TASK-1 does not form a functional channel in pulmonary artery smooth muscle cells.

  19. TASK-1 is important for the conduction of cardiac excitation and for the ventricular erpolarization under resting conditions of the heart.

  20. TASK channels are not required for the stimulation of aldosterone production by protons but their inhibition by physiological acidosis may contribute to full expression of the steroidogenic response.

Potassium Channel, Subfamily K, Member 3 (KCNK3) Protein Profile

Protein Summary

This gene encodes a member of the superfamily of potassium channel proteins that contain two pore-forming P domains. The encoded protein is an outwardly rectifying channel that is sensitive to changes in extracellular pH and is inhibited by extracellular acidification. Also referred to as an acid-sensitive potassium channel, it is activated by the anesthetics halothane and isoflurane. Although three transcripts are detected in northern blots, there is currently no sequence available to confirm transcript variants for this gene.
